golang 生成登录验证码

1. 第三方组件

github.com/mojocn/base64Captcha

在新版本中取消了 ConfigCharacter 这个配置方法，需要使用 DriverString

2. 代码

import ("image/color""github.com/mojocn/base64Captcha"
)// 设置自带的store
var store = base64Captcha.DefaultMemStore//生成验证码
func CaptMake() (id, b64s string, err error) {var driver base64Captcha.Drivervar driverString base64Captcha.DriverString// 配置验证码信息captchaConfig := base64Captcha.DriverString{Height:          60,Width:           200,NoiseCount:      0,ShowLineOptions: 2 | 4,Length:          4,Source:          "1234567890qwertyuioplkjhgfdsazxcvbnm",BgColor: &color.RGBA{R: 3,G: 102,B: 214,A: 125,},Fonts: []string{"wqy-microhei.ttc"},}driverString = captchaConfigdriver = driverString.ConvertFonts()captcha := base64Captcha.NewCaptcha(driver, store)lid, lb64s, lerr := captcha.Generate()return lid, lb64s, lerr
}//验证captcha是否正确
func CaptVerify(id string, capt string) bool {if store.Verify(id, capt, false) {return true} else {return false}
}
